AMALGAMATOR AND SETTLEF?.n

SPECIFICATION forming part of Letters Patent No. 278,035, dated May 22,1883.

' 'Application ined March 19, 188s. (No model.)

To alt whom it may concern:

Be it known that I, FREDERICK MORRIS, of the city and county of SanFrancisco, State of California, have invented an Improved Amalgamatorand Settler; and I hereby declare the the followingto be a full, clear,and exact description thereof.

My invention relates to certain improvements in amalgamators andsettlers, and in the construction thereof, the object of which is toprovide a strong` and water-tight device which shall be both economicaland durable. y

The nature of these improvements will hereinafter fully appear,reference being made to the accompanying drawings, in which- Figure l isa perspective view of my device with a portion of the vessell D brokenaway. Fig. 2 is a vertical section of same.

A represents a wooden platform, having a central vertical post, B,secured to it by bolts y b passing down through said post and platform.Around this post, upon the platform, are fitted segmental blocks a,forming a plate or disk which is the bottom of the vessel D. Theseblocks are nailed down to the platform. The reason for this constructionis that the bottom Vcannot shrink as much as if it were made of straightstrips, and it has a tendency rather to tighten in shrinking than toloosen. The sides of vessel D are made of staves d, the the lower endsof which are nailed to the periphery of the blocks a, forming thebottom. These staves are secured together by wooden hoops e, tacked toeach stave, one hoop covering thejoint of the other, and having its ownOn the bottom of the vessel I) arelaid segmental blocks h, or dies,which, by being made shorter than the' blocks c, forming the bottom,leave a peripheral channel or groove, j'. Their sides are also providedwith thin strips where by they are separated sufficiently to form shallow radiating grooves g.

Upon the top of post .B is secured a` cap, 1'.,

which serves as a step or bearing for a verti ca l shaft, I, which isjournaled therein. Upon this shaft is the crossframe,.J, of the mnller,in the. arms of which are secured rods K, eX- tending down within thevessel nearly to the blocks h.. Upon these rods are loosely fitted themuller shoes or blocks L. These may have a vertical play upon the rods,and are self-act- 'reach nearly to the bottom'.

vertically on the rods, according to material in the vessel. In order tokeep this vertical adjustment unimpaired,I1nust remove part of thestrain from the rods. I therefore connect each lnuller block or shoewith the cross-arm in advance ot' it by means of a rod, M, connected byloose links m and screw-eyes n. These latter may be adjusted as theshoeswear. In order to insure the shoes remaining as low `down as possible orgoing down again to their place, I place a weight, o, upon each.

The 4muller is revolved by the following` means: Upon top of shaft I isa crown'gear, P, meshing with a pinion, Q, upon a shaft', R, having adriving-pulley, S. The pinion Q, is placed upon a feather on the shaft,and has a collar, qfand a lever, q', secured thereto, in order to throwsaid pinion in or outof engagement with the crown-gear. This device isfor the purpose of settling ore-pulp in order to separate the` heavyparticles from the mud and slime after the ore has been ground. Therevolving muller keeps the pulpin a constant Vstate of agitation, inwhich the heavier particles separate and settle, and the waste materialrises and must be drawn o. The revolution of the muller causes the wasteafter sepa.- ration to be gradually forced to the center, and it is herethat I allow it to escape. two holes, fw, through the post and platform,which carry off the waste into a channel, under the platform. Theseholes are not made in the very top of the post, but in small ledge cutout nearly at the top, as shown. No sand will get in the step t'. Theseescapes are easy to make, and being right at the center and top,

I make ing, as they cannot fall away because 'the rods They thereforevvpass along the bottom and adjust themselves none but the worthlesspart, which has been Having thus described my invention, what I claim asnew, and desire to secure by Letters Patent., is

l. The platform A and central post, B, se-

cured thereto by bolts b, in combination with sa essaies the segmentalblocks a, fitted around the post and nailed to the platform, and thestaves d, nailed to the rims of the block and secured by wooden hoopse,- said blocks and staves forming` a vessel,'D, upon said platform andaround said post, substantially as and for the purpose herein described.1

2. The'platform A and post B, secured thereto, the Vessel D, formed'upon said platform, around the post, and the die-blocks h in saidvessel, in combination with the muller crossframe J,journaled on saidposi, the rods K, the muller-shoes L, loosely litted on the rods, andthe rods Mgcounccting each shoe with the arm of the muller-f'rame inadvance, substantially l as and for the purpose herein described.

o. The platform A, post- .l-l, with its discharge holes w, and theVessel D, built upon the platform, around the post, as herein described,in

combination with the die-blocks h, the muller cross-frame J, having rodsK and verticallyadjustable shoes L, connected each with a preceding armofthe cross-frame, and the means FREDERICK MORRIS.
